We report a fast single element nonvolatile memory that employs amorphous to crystalline phase change. Temperature change is induced within a single electronic element in confined geometry transistors to cause the phase change. This novel phase change memory (PCM) operates without the need for charge transport through insulator films for charge storage in a floating gate. GeSbTe (GST) was emplo...

Roughly speaking, an “optimization problem” is the task of finding an element x = xo of a given set X for which the value Φ(x) of a given function Φ : X 7→ R is minimal. Alternatively, the objective could be to find an element xγ ∈ X such that Φ(xγh) < γ, where γ ∈ R is a given threshold, or to give evidence to non-existence of such xγ does not exist. Among the most familiar optimization proble...

In recent years, steady improvement on both performance and energy efficiency of LSI systems by virtue of the miniaturization of CMOS process has been harder. However, lower power devices are still demanded, especially in growing IoT market. Although near-/sub-threshold voltage operation is one of promising ultra-low-power techniques, there are critical issues on exponential performance degrada...

Learning and convergence properties of linear threshold elements or perceptrons are well understood for the case where the input vectors (or the training sets) to the perceptron are linearly separable. Little is known, however, about the behavior of the perceptron learning algorithm when the training sets are linearly nonseparable. We present the first known results on the structure of linearly...

We have studied effects of additive elements into the channel layers of amorphous IGZO TFTs on threshold voltage shift issues under light illumination stress condition. By addition of Hf or Si element, the Vth shift under light illumination and negative bias-temperature stress and illumination stress conditions was drastically suppressed while the switching operation of TFTs using IGZO with Mn ...

Next Generation Sequencing (NGS) reads obtained by sequencing of the junction of a mobile element and the host flanking region from individuals in a population are typically mapped to a reference genome to determine the location of the mobile element-host junction. We propose a clustering pipeline for grouping such NGS data into clusters corresponding to the locations of integration sites in th...

The purpose of this study is to investigate the critical threshold stress causing bone resorption evaluated from strain measurement in vivo, comparing the various finite element models. In this study strains of miniplates used for mandibular fractures were measured once a week until the strains reduced. The maximum bite force for each patient was applied in the incisal, right molar and left mol...

The age-specific finite element human body models representing rib fracture were developed by the authors. They are limited, however, in quantitative evaluation of a strain that exceeds the predetermined threshold, i.e. the strain measured on the “fracture” model is censored. A “non-fracture” model can evaluate the value of the strain throughout the impact, but may be at a disadvantage when try...
